Description

Overview

The Siemens 5SJ4111-7HG40 is part of the SENTRON series, specifically engineered for the North American market and global applications requiring UL 489 certification. This miniature circuit breaker provides superior overcurrent and short-circuit protection. With a compact mounting depth of 70mm and "equal polarity" design, it is an ideal solution for space-constrained electrical panels in demanding environments.

Key Benefit

  • Global Compliance: Fully certified according to UL 489 and CSA, making it suitable for export-oriented machinery.

  • High Breaking Capacity: Capable of handling short circuits up to 14kA, protecting sensitive equipment from damage.

  • Space-Efficient: The 70mm depth allows for streamlined installation in standard control cabinets.

  • Trusted Reliability: Siemens engineering ensures long mechanical and electrical life cycles, reducing maintenance downtime.

Function

  • Overload Protection: Safely interrupts power in the event of sustained overcurrent.

  • Short-Circuit Protection: Instantaneous tripping during high-fault currents to prevent fire and equipment failure.

  • C-Trip Characteristic: Designed for circuits with moderate inrush currents, such as lighting, small motors, and control circuits.
